VISE ATTACHIVI ENT.

SPECIFICATION forming part of Letters Patent No. 631,538, dated August22, 1899. Application inea November 3o, 1398. serial No. 697.902. (Nomodel.)

ToaZZ whom t may con/cern,-

Be it known that I, JERRY D. DEOELLE, a

citizen of the United States, residing at Fort Collins, in the county ofLarimer and State of Colorado, have invented a new and useful ViseAttachment, of which the following is a specification. A

This invention relates to work-holding vises, and more especially tothat type of vises known as blacksmiths vises, which are speciallydesigned to facilitate the calking of horseshoes and upsetting metal forvarious purposes; and it has for its object to provide an improvedOperating attachment for the vise which will insure a quick action ofthe clamping-jaws and a powerful grip thereof on the work being operatedupon, while at the same time. enabling the vise to be controlled withbut little exertion on the part of the operator. j Y

To this end the invention contemplates an attachment capable of generalapplication to vises having relatively fixed and movable jaws andprovidingsimple and efficient means for opening and closing thevise-jaws without the use .of the ordinary screw commonly employed. y

With these and other objectsin view, which will readily appear asY thenature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinaftermore v fully described, illustrated, and claimed.

In the drawings, Figure 1 is a perspective view of a blacksmiths viseequipped with an operating attachment constructed in accord-H' ance withthe present invention.V Fig. 2 is a vertical sectional View of the viseand the attachment. Fig. 3 is a detail in perspective of the treadle andits supporting-bracket.

Fig. 4 is a detail in perspective of the lever,

the fulcrum-plate, and the .adjusting-bolt separated from each other.

Referring to the accompanying drawings, the numeral'l designates a viseof the type usually employed as a blacksmiths vise, which when in -useis mounted'in position on and at one side of the pedestal or block 2,

and said vise essentially consists of the relatively iXed and movablevise-jaws 3 yand 4, respectively, the fixed or stationary vise-jaw 3forming a continuation of the main standardor shank 5 of the vise, whichis arranged at one` side of the supporting pedestal or block 2. Both ofthe vise-jaws 3 and 4 are providedat their upper ends with opposinginturnedngripping-heads 6, between which the work to be operated upon isheld, and

the movable vise-jaw 4 is of a shorter length than the combined lengthof the standard or shank 5 and its jaw extension 3 and is pivoted at itslower end, as at 7, to the oifstanding supporting arm or yoke 8, rigidlyconnected with the standard or shank y5 of the fixed jaw. l j M In thepresent invention the vrelatively fixed and movable jaws 3 and 4 of thevise are normallyseparated by means of a 'substantially V-shapedleaf-spring 9, interposed between the jaws and provided at itsextremities with yokes 10, embracing the inner edges thereof. The lowerend or apex of the spring 9 usually rests upon the oistandingsupporting-arm 8 for the movable jaw to prevent downward displacement ofthe spring,while lateral displacement is prevented by the en gagement ofthe yokes 10 thereof with the jaws.

Above the plane of the upper ends of the Aend with a threaded terminal13, receiving thereon the.nut 14, bearing on the washer 15, placedagainst the adjacent side of the fixed or stationary jaw 3 of thedevice, and by means of which before mounting against a support the jawsmay be primarilyadjusted a suitable distance. The opposite end of thebolt '12, which extends through the opening 11 in the movable jaw 4, isprovided with a fork having oppositely-located pivot-ears 16, betweenwhich is pivotall y mounted the lever 17, at one corner thereof. Thelever is of an approximately triangular shape, and the corner thereofbelow its pivotal connection with the bolt 12 is pivotally-mountedbetween the pivot-ears 18 of the fulcrum-plate 19. This fulcrum plate isarranged ilat against the Outer side of the movable jaw4and isdetachably clamped thereto by means of the clipbolt 20, embracing saidjaw and bolted in the perforated side wings 2l of the fulcrum-plate.

IOO

The outer extremity of the lever 17, beyond its connection with the boltand the lnovable vise-jaw, has pivotally connected thereto one end ofthe operating-rod 22, the lower end of which rod is similarly connectedto the pivotarm 23, projected centrally from the inner side of askeletontreadle-plate 24. The skeleton treadle-plate 24 is of a substantial Ushape and in rear of the central pivot-arm 23 thereof has the pivot-studconnections with opposite ends of the supporting-bracket 26, detaehablyheld to the standard or shank 5 of the vise by means of clip-bolts 27,enibracing said standard or shank and bolted through the said plate 26.

Normally the jaws of the vise are separated by the spring 9; but whenthe work is placed between the jaws the operator places his foot on thetreadle and depresses the latter, which movement rocks the lever 17 onits fulcrum connection with the adjusting-bolt 12 and moves the jaw 4;inward or toward the fixed or stationary jaw 3, thereby securing a veryquick, positive, and firm adjustment of the movable jaw of the vise.

From the foregoing it will be observed that all parts of the attachmentare readily separable, so that lthe same can be easily iitted to a visehaving a relatively fixed and movable jaw.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

l. In a vise, the combination of fixed and movable jaws, the fixed jawhaving an offset intermediate its length to which the movable jaw ispivoted, a substantiallyV-shaped spring interposed between the jaws andhaving its reduced portion or angle resting on the offset and its freeends or extremities formed with embracing-yokes freely movable over theopposite jaws, said spring normally separating the jaws, anadjusting-bolt having positive connection with the ixed jaw andextending through an opening in' the movable jaw, a lever connected tothe outer portion of the bolt and also to a part of the movable jawbelow the said bolt, and means for actuating said lever attached to theouter portion of the latter.

2. In a vise, the combination with Iixed and y movable jaws, of a springnormally separating said jaws, an adjusting-bolt having positiveconnection with the fixed jaw and extending through an opening in themovable jaw, a lever having pivot-ears respectively connected to theouter free end of the said bolt and to a part of the movable jaw belowthe said bolt, and a treadle connection movably attached to the outerportion of the said lever.

3. In a vise, the combination with the iixed and movable jaws, of a bolthaving an adj ustable connection at one end with the fixed jaw andloosely extending through an opening in the movable jaw, said bolt beingprovided with a forked end at one side of the movable jaw, afulcrum-plate detachably bolted to the movable jaw, a lever pivotallyconnected to the fork of the bolt and also to the fulcrumplate, asupporting-bracket detachably bolted to the standard of the vise, atreadle pivotally mounted on said standard, and a rod connection betweenthe treadle and the lever, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

JERRY D. DECELLE.
